enrr'rnn BAR non Application filed February The present invention relates to an im proved gripper bar for use on platen printing presses, and has for its principal object to provide an adjustable structure capable of allowing the gripper bar to be adjusted or swung in relation to the gripper holder so as to extend at various angles therefrom and also permits the" gripper bar to be lengthened or shortened as may be desired.

Another very important object of the invention is the provision of a gripper barof this nature which is exceedingly simple in its construction, easy to manipulate in its various adjustments, not likely to easily become out of order, strong, durable, and

otherwise well adapted to the purpose for which it is designed. 1

With the above and numerous other Ob, jects in view as will appear as the description proceeds, the invention resides in certain novel features ofv construction, and in the combination and arrangement of parts as will be "hereinafter more fully described and claimed.

Inthe drawing:,

Figure 1 is asectional view through a gripper holder showing one of my improved gripper bars, I j

Fig. 2 is a plan view of the gripper bar,

Fig. 3 is an edge View of a modification of the gripper bar, and

Fig. 4 is a bottom plan view of said modification.

Referring to the drawing in detail, it will be seen that 5 designates a platen having the usual gripper holder 6 mounted thereon with a plurality of screws 7 engageable therewith for holding the gripper bars in place. I have just illustrated the mounting of a single gripper bar, for the purposes of the present invention, wherein the improvement lies in the gripper bar per se. i

Referring to the embodiment of the gripper bar as is illustrated in Figs. 1 and 2, it will be seen that 8 designates an elongatecl shank forming the gripper bar ;proper,and-9 designates a plate which is provided on its surface with an elongated longitudinally extending groove 10, and a, similarly extending slot 11. The shank 8.

is slidably receivable in the groove 10 and a screw 12 pierces the slot 11 and engages the shank 8 so that the shank 8 may be held in different-adjusted position in rela as this will suffice.

tion to the platea9dfor lengthening and shortening the gripper bar.

The plate 9 is proviled with an aperture 7 V or opening 13. A washer 14 is provided stud 17 it will be seen that the plate 9 may be swung to the desired angle in relation to the gripper holder 6, and when the screw 7 is tightened,the teeth 16 of the washer 14; will engage the teeth 18 of the stud 1.7 thereby locking theplate 9v in the adjusted posit-ion.

. Referring now particularly to the en1-' .bo'diment shown in Figs. 3 and 1, it will be seen that a plate 9 is provided with a flange at one end for engaging the gripper holderin a similar manner to the flange 15 of the washer 14:. vided'with an opening 13 adjacent the flanged end 15, and on its under surface The opening 13 is adapted to receivethe screw 7. The similarity between the em bodiments will be apparent hereinafter.

It is thought that the construction, operation, and advantages of this invention will now be clearly understood without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and, the above description.

It will be apparent that changes in the details of construction, and in the combinacan and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter The plate'9" is prot is provided with anelongated longitudiclaimed onsacrificing any of its advantages.

Having. thus described my invention, What" I claim as new is A gripper bar of the class described including an oblongv plate provided onhi'ts under surface With an elongated longitudinally extending groe i e' arranged along the median longitudinal dimension of the plate and a slot coincident with a portion of said groove and extending longitudinally therewith, a sh'ank'forming'the' gripper bar relationrto said plate said plate being provided with an openinu for receiving the screw 0 a :ri" per 1101 er.
